F​iona is responsible for at least five deaths across the Caribbean. Two people were killed in Puerto Rico after being swept away by flooded rivers. One person died in the Dominican Republic after they were struck by a falling tree during the storm, and another was killed in the country by a falling electric post. In the French Territory of Guadeloupe, one man died after being carried away by floodwaters.

O​fficials reported minimal damage and no deaths in Turks and Caicos, though the storm passed close to the capital island of Grand Turk Tuesday morning. The government had issued a curfew and urged evacuations from flood-prone areas prior to the storm.

T​he hurricane made its second landfall in the Dominican Republic on Monday, dropping torrential rain, damaging roofs and scattering debris across roads.

F​iona is likely to track close to Bermuda late Thursday or Friday, and then head to Atlantic Canada on Saturday.​ The Canadian Hurricane Center said on Wednesday that the storm was posing as "a potentially severe event for Atlantic Canada."
